This past week brought 'Supernatural' back from a brief hiatus to tackle the menace of "Meta Fiction," while two weeks time will introduce us to the "Bloodlines" spinoff we've heard so much about, but in the meantime Sam and Dean are calling in an old friend. Sheriff Mills (Kim Rhodes) returns to enlist the boys' help in taking down vampires for "Alex Annie Alexis Ann," but what do the full set of photos reveal?

Judging by the above clip from "Alex Annie Alexis Ann," we'd guess that the four girls have something to do with disappearances over the last few years, some of whom seem to ingrain themselves with vampires out of a bizarre supernatural Stockholm Syndrome. In the meantime, Sam and Dean seem to get themselves in something of a pickle with the aforementioned nest, while Sheriff Mills is nowhere to be seen.

Here's what The CW had to say of next Tuesday's "Alex Annie Alexis Ann":

SHERIFF MILLS TRIES TO SAVE A YOUNG GIRL FROM A VAMPIRE NEST — Sheriff Mills (guest star Kim Rhodes) calls Sam (Jared Padalecki) and Dean (Jensen Ackles) after she kills a vampire who attacked a prisoner named Annie (guest star Katherine Ramdeen). They discover Annie was kidnapped by a family of vampires who use her as bait to lure in humans they can then feed on. Sheriff Mills tries to rescue Annie from her captors, but finds out the hard way that family always comes first.

Only four episodes remain in the ninth (but not final) season of 'Supernatural,' so what do we think? Will "Alex Annie Alexis Ann" kill a bit of time before the endgame, or come up short? Check out the photos below, and give us your predictions in the comments!
